SAFETY GUN TRIGGER Filed July 1, 1943 Patented July 10, 1945 UNlTED STATES PATENT OFFICE SAFETY ZZZ TLIGGER Application July 1, 1943, Serial No. 493,101

4 Claims.

This invention relates to a safety gun trigger, and has for one of its objects the production of a simple and eflicient means for positively locking the trigger of a gun against movement and thereby preventing the accidental discharge of the gun. I

A further object of this invention is the production of a simple and efiicient three-point safety device for looking a trigger of a gun against accidental movement.

Other objects and advantages of the present invention will appear throughout the following specification and claims.

In the drawings:

Figure 1 is a fragmentary top plan view of a portion of a gun showing the safety means located thereon;

Figure 2 is a horizontal longitudinal sectional view showing the parts in a locked position;

Figure 3 is a si milar view showing the parts in a released position;

Figure 4 is a transverse sectional view taken on line 4-4 of Figure 2;

Figure 5 is an end elevational view. of the trigger lock;

Figure 6 is an enlarged side elevational view of the trigger lock, a portion of the trigger also being shown;

Figure 7 is a detail perspective view of the means for locking and'unlocking the pull rod;

Figure 8 is a fragmentary side elevational view of the inner end of the pull rod.

By referring to the drawing, it will be seen that It) designates the stock of the gun which carries the conventional barrel I I. The stock I8 of the gun is provided near'its forward end with a pocket I2 in which is mounted a box I3. A button-receiving socket I4 is formed in one side of the stock I0 communicating with the pocket I2, and a button-receiving socket I5 is formed in the opposite side of the stock In communicating with the pocket I2, and in offset alignment with the socket I4. A push-button I6 is mounted within the socket I4 and a push-button I1 is mounted in the socket I 5. A plunger rod I8 is carried by the push-button I6 and supports a pivot link I9. A spring 20 is interposed between the push-button I6 and the box I3, to normally urge the button I6 outwardly and this button I6 may be provided with a suitable flange 2| to limit the outward movement of the button I6.

A similar spring 22 is carried by the button I I,

and this'button I1 is constructed similarly to the button I6. The particular construction or design of the buttons l 6 and I I may be varied without departing from the spirit of the invention.

The push-button II is provided with a plunger rod 23 and the plunger rod 23 extends into the box I3 for engaging and locking the rod 24 in a safety position. The plunger rod I 3 extends into the box I3, and the plunger rod I8 extends in an opposite direction to the rod 23 and transversely of the box l3, as shown, and when operated this'plunger rod I8 will shift the rod .24 longitudinally to release the plate 32 from a locking position relative to the trigger 39.

A pull rod 24 extends longitudinally of the stock II] and carries an expansion spring 25 at its forward end, the spring 25 being located in the socket 26 which extends longitudinally of the forward end of the stock Ill. The spring 25 is adapted to normally pull the pull rod 24 forwardly. The link I9 which is pivotally connected to the rod I8 is also pivotally connected, as at- 21, to the pull rod 24 and is inclined rearwardly and away from the push-button I6. The rod 24 is provided with a transversely extending notch 28 in spaced relation to the link I 3 and this notch 28 is adapted to receive the pin 29 which is carried by the plunger rod 23 for the purpose of holdingor locking the rod 24 in a set position.

The rod 24 is provided with a knob 3ii'at its rear end in front of which knob 30 is fitted a hook 3| of the trigger-releasing and engaging slideplate 32. The rod 24is provided with a shank 33 near the knob 33 for the purpose of receiving the hook 3|. This hook 3| is carried by the forward end of the plate 32 and this plate 32 .is provided with a pair of longitudinally extending slots 34 for receiving the retaining screws 35. The retaining screws 35 are adapted to secure the plate 32 to the conventional bolt of the gun 36 indicated in dotted lines. The plate 32 is provided at its rear end with a depending lip 31 which is adapted to engage the shoulder portion 38 of the trigger 39 and hold the trigger against movement until the lip 31 and plate 32 are shifted to a disengaging position.

The operation of the device is as follows:

The parts are normally in the position shown in Figures 1, 2 and 6.. When it is desired to fire the gun, the left hand of the operator will engage the forward portion of the stock I0 adjacent the push-buttons I6 and I! with his right hand and trigger finger adjacent the trigger 39. The push-button I1 is then pushed inwardly, thereby releasing the pin 29 from engagement withthe notch 26. The push-button I6 is then pressed inwardly and this movement will cause the link thereby permitting the trigger 39 to be swung for releasing the firing pin of the gun.

It should be understood that the present device may be applied to various types of fire-arms, and only those portions of the gun which are essential to all types have been illustrated in view of the fact that the present invention re-' lates to a means for locking the trigger against swinging movement until the trigger is first mechanically released by the operation of the pushbuttons l6 and I1.

understood that the bolt, the particular type of trigger, and firing pin control mechanism may be varied without departing from the spirit of the invention, and also that certain detail changes in design may be employed so long as these changes fall within the scope of the appended claims.

Having described claimed is:
